Implementation mode one
Please refer to fig. 2, which is a method for determining a HARQ-ACK codebook according to an embodiment of the present application, the method includes:
step S210, the network equipment sends trigger information to the user equipment, wherein the trigger information is used for indicating the user equipment to carry out single hybrid automatic repeat request response One-Shot HARQ-ACK feedback; optionally, the trigger information includes DCI information of downlink control information sent by the network device to the user equipment;
step S220, the user determines a Type-3HARQ-ACK codebook; specifically, the user equipment determines HARQ-ACK information of a target Transport Block (TB) in a target HARQ process in a Type-3HARQ-ACK codebook according to data scheduling information corresponding to the target TB in the target HARQ process; the Type-3HARQ-ACK codebook comprises HARQ-ACK information corresponding to all HARQ processes on all configured carriers in a physical uplink control channel PUCCH group;
step S230, the network device receives the Type-3HARQ-ACK codebook fed back by the user equipment. Wherein, the Type3 codebook comprises two types: type 1 is One-Shot HARQ feedback carrying NDI (New Data Indicator); type 2 is One-Shot HARQ feedback that does not carry NDI. The network device may configure a UE (User Equipment) through an RRC (Radio Resource Control) signaling, so that the UE carries NDI information or does not carry NDI information when performing HARQ feedback.
Type 1: One-Shot HARQ feedback carrying NDI
1) And the user equipment feeds back the NDI information and the HARQ-ACK information corresponding to the HARQ process number received for the last time.
2) If a HARQ process does not have prior NDI information, the ue assumes that NDI is 0.
3) One NDI value for each TB.
Type 2: One-Shot HARQ feedback without NDI
1) And the user equipment feeds back HARQ-ACK information corresponding to the HARQ process number and does not feed back corresponding NDI information.
2) For a certain HARQ process, if the user equipment performs ACK feedback once, the state of the HARQ process should be reset.
The data scheduling information may be used to indicate whether the target TB is currently scheduled for new transmission, retransmission, or not scheduled.
The HARK-ACK information includes ACK information or NACK information.
Optionally, the data scheduling information corresponding to the target TB includes one of first information, second information, and third information. Wherein:
the first information includes: the target TB is currently scheduled to transmit newly;
the second information includes: information that the target TB is currently scheduled for retransmission;
the third information includes: information that the target TB is not currently scheduled.
Optionally, the information that the target TB is currently scheduled to newly transmit includes: the current NDI information of the target TB has a different value relative to the last NDI information, or the target TB is a TB in a semi-persistent scheduling (SPS) PDSCH.
Optionally, the information that the target TB is currently scheduled for retransmission includes: the current NDI information of the target TB has the same value relative to the last NDI information, or the target TB is a TB in the SPS PDSCH and the value of the NDI information is 1.
Optionally, the information that the target TB is not currently scheduled includes: the target TB does not currently correspond to NDI information, or the target TB does not currently correspond to NDI information and is not a TB in the SPS PDSCH.
Optionally, the target TB does not currently correspond to DCI information, including: the target TB is not currently indicated by the DCI NDI information.
Specifically, for data transmission scheduled by PDCCH, the DCI includes an NDI field, or each TB corresponds to an NDI information. For a certain TB label in a scheduled HARQ process, if the NDI information corresponding to the TB label received by the terminal device is inverted relative to the NDI information corresponding to the TB label received by the terminal device last time, it indicates that the TB currently received by the terminal device is a new transmission; if the terminal device receives the NDI information of the TB label without being turned over relative to the NDI information corresponding to the TB label received by the terminal device last time, it indicates that the TB currently received by the terminal device is a retransmission.
For data transmission without PDCCH Scheduling, such as transmission on SPS (Semi-Persistent Scheduling) configuration resources, the SPS PDSCH transmitted on the downlink SPS configuration resources only includes initial transmission. If the initial transmission of a certain HARQ process fails and needs to be retransmitted, the Network device may schedule the same HARQ process through DCI scrambled by a CS-RNTI (Configured Radio Network Temporary Identifier), and set the NDI field to "1". That is, if the terminal device receives DCI scrambled by the CS-RNTI and the NDI field is set to "1", the terminal device considers the HARQ process scheduled by the DCI as retransmission. Or, the TB with the NDI field set to "1" transmitted in the HARQ process is the TB in the SPS PDSCH.
Optionally, the information that the target TB is currently scheduled to newly transmit includes: the terminal equipment receives DCI, wherein the DCI comprises scheduling information of the target TB in the target HARQ process, and the NDI information corresponding to the target TB is turned over relative to the NDI information corresponding to the target TB in the last target HARQ process; or, the terminal device receives the SPS PDSCH corresponding to the target TB in the target HARQ process.
Optionally, the information that the target TB is currently scheduled for retransmission includes: the terminal equipment receives DCI, wherein the DCI comprises scheduling information of the target TB in the target HARQ process, and NDI information corresponding to the target TB is not turned over relative to NDI information corresponding to the target TB in the last target HARQ process; or, the terminal device receives DCI scrambled by CS-RNTI, wherein the DCI comprises scheduling information of the target TB in the target HARQ process, and NDI information corresponding to the target TB is set to be '1'.
Optionally, the information that the target TB is not currently scheduled includes: the terminal device does not receive DCI comprising scheduling information of the target TB in the target HARQ process; or the terminal device does not receive the SPS PDSCH corresponding to the target TB in the target HARQ process.
Optionally, the information that the target TB is currently scheduled includes: the information that the target TB is scheduled to be newly transmitted currently or the information that the target TB is scheduled to be retransmitted currently.

Optionally, in the One-Shot HARQ feedback, the ue may also be configured through an RRC signaling, so that when the ue performs HARQ feedback, it is determined whether CBG-based feedback is to be performed for a carrier configured with CBG (Code Block Group) transmission.
Optionally, when the user equipment performs CBG-based feedback on the carrier, no TB-based feedback is performed.
Optionally, the HARQ codebook arrangement order follows the following principle: first CBG or then TB, then HARQ process, and finally carrier. For example: and for each carrier in the ascending sequence arrangement, feeding back HARQ-ACK information bits corresponding to each TB of each HARQ process in which the HARQ processes are arranged in the ascending sequence.
Optionally, if the user equipment is configured to feed back One-Shot HARQ-ACK information according to the CBG and the target cell corresponding to the target HARQ process is configured with the CBG feedback length, determining the bit length of the HARQ-ACK information of the target TB according to the CBG feedback length; otherwise, determining the bit length of the HARQ-ACK information of the target TB according to the TB feedback length.

Figure PCTCN2020087679-APPB-000001
Figure PCTCN2020087679-APPB-000002
Figure PCTCN2020087679-APPB-000003
referring to fig. 3, in the prior art, for a Type-3HARQ-ACK codebook that does not include NDI, in a feedback process according to CBG, for a target TB in a target HARQ process, if the UE has reported ACK before, the UE sets a corresponding HARQ-ACK information bit to NACK; otherwise, the UE feeds back the corresponding HARQ-ACK information. In the process, when the same HARQ process is scheduled in both the two Type-3HARQ-ACK codebook feedback processes and the corresponding decoding information is ACK, the second Type-3HARQ-ACK codebook does not include ACK information obtained when the HARQ process is scheduled for the second time, but instead, HARQ-ACK information set as NACK after ACK information is fed back in the last scheduling. Thereby causing the Type-3HARQ-ACK codebook feedback to be incorrect.
Similarly, for the Type-3HARQ-ACK codebook without the NDI, in the feedback process according to the TB, for the target TB in the target HARQ process, if the UE has reported NACK before, the UE feeds back the corresponding HARQ-ACK information; otherwise, the UE sets the corresponding HARQ-ACK information bit as NACK. In the process, when the same HARQ process is scheduled in both the two Type-3HARQ-ACK codebook feedback processes and the first decoding information is ACK, the second Type-3HARQ-ACK codebook does not include ACK information obtained when the HARQ process is scheduled for the second time, but instead, HARQ-ACK information set as NACK after ACK information is fed back in the last scheduling. Thereby causing the Type-3HARQ-ACK codebook feedback to be incorrect.
In the first embodiment of the present application, as shown in fig. 4, when feeding back HARQ-ACK information bits for each TB, HARQ-ACK information included in a feedback Type-3HARQ-ACK codebook is determined according to data scheduling information corresponding to a target TB in a target HARQ process. Instead, the user terminal directly sets the HARQ-ACK information as NACK if ACK has been reported. Thus, the Type-3HARQ-ACK codebook is ensured to be correctly reset or generated.
